Question: There is a group of islands among which is one that received COM status in 2007 alongside St Barts. When did the people who received support from Posen in the Franco-Prussian War come to those islands?
Context: Document 1: Saint Barthélemy: On 7 February 2007, the French Parliament passed a bill granting COM status to both St. Barthélemy and (separately) to the neighbouring Saint Martin. The new status took effect on 15 July 2007, when the first territorial council was elected, according to the law. The island has a president (elected every five years), a unicameral Territorial Council of nineteen members who are elected by popular vote and serve for five-year terms, and an executive council of seven members. Elections to these councils were first held on 1 July 2007 with the last election in March 2012.
Document 2: French West Indies: Pierre Belain d'Esnambuc was a French trader and adventurer in the Caribbean, who established the first permanent French colony, Saint - Pierre, on the island of Martinique in 1635. Belain sailed to the Caribbean in 1625, hoping to establish a French settlement on the island of St. Christopher (St. Kitts). In 1626 he returned to France, where he won the support of Cardinal Richelieu to establish French colonies in the region. Richelieu became a shareholder in the Compagnie de Saint - Christophe, created to accomplish this with d'Esnambuc at its head. The company was not particularly successful and Richelieu had it reorganized as the Compagnie des Îles de l'Amérique. In 1635 d'Esnambuc sailed to Martinique with one hundred French settlers to clear land for sugarcane plantations.
Document 3: Franco-Prussian War: In the Prussian province of Posen, with a large Polish population, there was strong support for the French and angry demonstrations at news of Prussian-German victories—a clear manifestation of Polish nationalist feeling. Calls were also made for Polish recruits to desert from the Prussian Army—though these went mainly unheeded. An alarming report on the Posen situation, sent to Bismarck on 16 August 1870, led to the quartering of reserve troop contingents in the restive province. The Franco-Prussian War thus turned out to be a significant event also in German–Polish relations, marking the beginning of a prolonged period of repressive measures by the authorities and efforts at Germanisation.
Document 4: Princess Juliana International Airport: Princess Juliana International Airport is the main airport on the Caribbean island of Saint Martin/Sint Maarten. The airport is located on the Dutch side of the island, in the country of Sint Maarten. In 2015, the airport handled 1,829,543 passengers and around 60,000 aircraft movements. The airport serves as a hub for Windward Islands Airways and is the major gateway for the smaller Leeward Islands, including Anguilla, Saba, St. Barthélemy and St. Eustatius. It is named after Queen Juliana, who landed here while still only heir presumptive in 1944, the year after the airport opened. The airport has very low-altitude flyover landing approaches, owing to one end of its runway being extremely close to the shore and Maho Beach. There is also an airport on the French side of the island, in the French Collectivity of Saint Martin, called Aéroport de Grand Case or L'Espérance Airport.
